University of Southampton Electronics and Computer Science Background/Motivations Realisation that grid tech. can be used within increasing number of domains –E-business –Computer games industry (Butterfly.net) –Military (simulations) Drive towards a more pervasive grid Existing grid tech. sophisticated -> significant complexity –To what extent can this be reduced?

University of Southampton Electronics and Computer Science Executor: Requesting a Job Client directs browser to jobRequest page, which continually refreshes When job is available: –Applet task moved to working dir., job id prefix –Applet is packaged in web page and delivered When job is finished, waits as before

13
University of Southampton Electronics and Computer Science Executor: Returning Results Once applet has completed, uploads results to jobSubmitResults on server Applet removed from working directory Results placed into complete directory with job id prefix

14
University of Southampton Electronics and Computer Science Exploitation Issue Applets can be ‘hidden’ on any web page Use technology to steal processor cycles from visiting machines’ browser Attach to popular web pages Cycleware

16
University of Southampton Electronics and Computer Science Further Future Work Load balancing between multiple servers –Execution nodes get passed around servers until job received –Busy servers redirect job submissions to less busy servers
